Definitions
- the subject matter described herein relates generally to neutral beam injectors and, more particularly, to a photon neutralizer for a neutral beam injector based on negative ions.
- a traditional approach to produce a neutral beam from a negative ion H-, D- beam for plasma heating or neutral beam assisted diagnostics is to neutralize the negative ion beam in a gas or plasma target for detachment of the excess electrons.
- this approach has a significant limitation on efficiency.
- the neutralization efficiency in the gas and plasma targets will be about 60% and 85%, respectively [G. I. Dimov et al., 1975, Nucl. Fusion 15, 551], which considerably affects the overall efficiency of the injectors.
- the application of such neutralizers is associated with complications, including the deterioration of vacuum conditions due to gas puffing and the appearance of positive ions in the atomic beam, which can be significant in some applications.
- Photodetachment of an electron from high-energy negative ions is an attractive method of beam neutralization. Such method does not require a gas or plasma puffing into the neutralizer vessel, it does not produce positive ions, and it assists with beam cleaning of fractions of impurities due to negative ions.
- the photodetachment cross section is well known [see, e.g., L.M.Branscomb et al, Phys. Rev. Lett. 98, 1028 (1955)].
- the photodetachment cross section is large enough in a broad photon energy range which practically overlaps all visible and near IR spectrums.
- Such an optic resonator needs mirrors with very high reflectance and a powerful light source with a thin line, and all of the optic elements need to be tuned very precisely.
- the reflectance of the mirrors is required to be not less than 99.96%
- the total laser output power is required to be about 800 kW with output intensity of about 300W/cm 2
- the laser bandwidth is required to be less than 100 Hz. It is unlikely that such parameters could be realized together.
- Embodiments provided herein are directed to systems and methods for a non-resonance photo-neutralizer for negative ion-based neutral beam injectors.
- the non-resonance photo- neutralizer described herein is based on the principle of nonresonant photon accumulation, wherein the path of the photon becomes tangled and trapped in a certain space region, i.e., the photon trap.
- the trap is preferably formed as two smooth mirror surfaces facing each other with at least one surface being concave.
- the trap is preferably elliptical in shape.
- a confinement region of the trap is a region near a family of normals that are common to both mirror surfaces of the trap.
- the photons with a sufficiently small angle of deviation from the nearest common normal are confined.
- the shape of the trap may be one of spherical, elliptical, cylindrical, toroidal, or a combination thereof.
- photon beams with a given angular spread along and across the trap are injected through one or more small holes in one or more of the mirrors.
- the photon beams can be from standard industrial power fiber lasers.
- the photo neutralizer does not require high quality laser radiation sources pumping a photon target, nor does it require very high precision adjustment and alignment of the optic elements
- FIGURE 1 is a schematic of a non-resonance photon trap.
- FIGURE 2 is a schematic of a quasiplanar adiabatic optical trap.
- FIGURE 3 is a perspective view schematic of the quasiplanar adiabatic optical trap shown in Figure 2.
- FIGURE 4 is a trace of a single ray in the photon trap with a random angle from -3° to 5° in the XY plane, and -5° to 5° along the trap, the number of reflections is 4000.
- the cone angle of end mirrors is about 3°.
- FIGURE 5 illustrates an example of the surface intensity distribution and its cross profile in the middle of the trap.
- FIGURE 6 is a chart showing the degree of neutralization (dotted line) and overall neutralizer efficiency (continuous curve) vs laser injection power.
- FIGURE 7 is a plan view of a negative ion-based neutral beam injector layout.
- FIGURE 8 is a sectional isometric view of the negative ion-based neutral beam injector shown in Figure 7.
- Embodiments provided herein are directed to a new non-resonance photo-neutralizer for negative ion-based neutral beam injectors.
- a detailed discussion of a negative ion-based neutral beam injector is provided in Russian Patent Application No. 2012137795 and PCT application No. PCT/US2013/058093, which are incorporated herein by reference.

- FIG. 1 an embodiment of a non-resonance photon trap 10 is shown in Figure 1.
- the trap 10 comprises a bottom flat mirror 20 and a top concave mirror 30.
- a photon ⁇ with a small angle to vertical axes within the trap 10 will develop with each reflection from the upper mirror 30 some horizontal momentum
- the stability condition is ' ' , from which photons confinement in a geometric optic, when taking into account non-negativity of value R , is determined as
- Relation (10) determines the region filled by photons.
- the trap 10 preferably comprises a bottom or lower mirror 20 at the bottom of the trap 10 that is planar or flat in shape, and an upper mirror assembly 30 comprising a central mirror 32 that is cylindrical in shape, and a pair of outer mirrors 34 that are conical in shape and coupled to the ends of the central mirror 32.
- an ion beam FT is passed along the photon trap. The sizes are taken from the characteristic scales of a single neutralizer channel of a beam injector for the International Thermonuclear Experimental Reactor (ITER).
- ITER International Thermonuclear Experimental Reactor
- photons beams with a given angular spread along and across the trap 10 can be injected through one or more small holes in one or more mirrors.
- photons beams with a given angular spread along and across the trap 10 can be injected through one or more small holes in one or more mirrors.
- a ytterbium fiber laser total power above 50 kW it is possible by using a ytterbium fiber laser total power above 50 kW
- the radiation beam with necessary angular spread can be prepared from fiber laser radiation by special adiabatic conical or parabolic shapers.
- radiation with a spread of 15° from fiber and 03 ⁇ may be transformed to 5° and 01 mm, which is sufficient for the neutralizer trap 10 described herein.
- the degree of neutralization is representable as where d is the width of the neutralization region, Eo is the photon energy, V is the velocity of the
- the neutralization efficiency of D- flux by the laser with overall efficiency TJi may be determined as where P is the negative ion beam power.
- the efficiency increases with growth of D- beam power.
- the efficiency (13) and degree of neutralization (12) are shown in Figure 6. This curve has been calculated for a single channel gas neutralizer in ITER injectors, in which 10 MW part is passed. Thus, in such an approach nearly 100% neutralization can be achieved with very high energetic efficiency of about 90%.
- ITER neutral beam injector has a 58% neutralization [R. Hemsworth et al.// Nucl. Fusion. 2009, v.49, 045006] and correspondently the same efficiency.
- the overall injector efficiency while taking into account accelerator supply and transport losses has been estimated by Krylov [A.
- FIG. 7 A preferred arrangement of an example embodiment of a negative ion-based neutral beam injector 100 is illustrated in Figures 7 and 8.
- the injector 100 includes an ion source 110, a gate valve 120, deflecting magnets 130 for deflecting a low energy beam line, an insulator-support 140, a high energy accelerator 150, a gate valve 160, a neutralizer tube (shown schematically) 170, a separating magnet (shown schematically) 180, a gate valve 190, pumping panels 200 and 202, a vacuum tank 210 (which is part of a vacuum vessel 250 discussed below), cryosorption pumps 220, and a triplet of quadrupole lenses 230.
- the injector 100 comprises an ion source 110, an accelerator 150 and a neutralizer 170 to produce about a 5 MW neutral beam with energy of about 0.50 to 1.0 MeV.
- the ion source 110 is located inside the vacuum tank 210 and produces a 9 A negative ion beam.
- the vacuum tank 210 is biased to -880 kV which is relative to ground and installed on insulating supports 140 inside a larger diameter tank 240 filled with SF6 gas.
- the ions produced by the ion source are pre-accelerated to 120 keV before injection into the high-energy accelerator 150 by an electrostatic multi aperture grid pre- accelerator 111 in the ion source 110, which is used to extract ion beams from the plasma and accelerate to some fraction of the required beam energy.
- the 120 keV beam from the ion source 110 passes through a pair of deflecting magnets 130, which enable the beam to shift off axis before entering the high energy accelerator 150.
